Also, how many angles and sides at the minimum do you need to find the area?

1/2 b*h
You need
2 angles and a side OR
2 sides and an angle OR
3 sides
Sides A,B, C angles a,b,c area is 1/2 A*B cos c,
A cos c-= C cos(180-a)
depending on the information other formula a more useful

It depends on what all is given. You can find the area if any of the 3 components (3 sides and 3 angles) are given. However you cant find the area if 3 angles are given, ie at least 1 side must be given.

A=1/2bh
Area= 1/2 base times height

The only general formula I can give you is 1/2*height*base.
There is no other formula that can be applied for all kinds of triangles.
I have searched for it several times when I was at school.

a=half of base X height.
You don't need any angles. Just one side, and the length in which the midpoint of that side connects to the opposite angle. (height)

Area = 1/2 of Base (B) x Height (H)
a = 1/2bh

area of triangle=1/2*base*height
its enough to knowthe lenght of any one side,
and the distance of the same from the opposite vertex.

two sides and the angle between them are enough.
If the sides are a,b and the included angle is C then area is
1/2 * a*b* sin C

i am not sure about this formula but you can further search for heron's formula.
square root of [{s-a}{s-b}{s-c}] where a,b,c are dimensions of the triangle's sides and s=a+b+c/2
